== Publication Abstract from PubMed ==
The effect of halogen-to-hydrogen bond substitution on the binding energetics and biological activity of a human aldose reductase inhibitor has been studied using X-ray crystallography, IC50 measurements, advanced binding free energy calculations, and simulations. The replacement of Br or I atoms by an amine (NH2) group has not induced changes in the original geometry of the complex, which made it possible to study the isolated features of selected noncovalent interactions in a biomolecular complex.
